I've posted this in another thread but I'll post it again here. Go to e b a y and search item # 230818682873 seller is supermedicalsupply. It's currently 23.80/gal with free shipping. They ship out really quick and I received it next day because they have warehouses scattered across the US.
Good to know! Will keep that in mind next time I need it, $27.24 including shipping on Amazon was the lowest price I could find when I bought it. I looked on ebay but didnt see that add at the time.
